Title: Improvements in or relating to the manufacture of an artificial leather-like composition
IPC: C08L89/06
Filed: 1932-09-07
Abstract: In the manufacture of compositions by the impregnation of waste leather with rubber dispersions and subsequent drying, the drying is carried to such a degree as to eliminate the water contained in the fibres.  Waste leather is mixed with a rubber dispersion and heated until the water of the dispersion is driven off, and the mass appears to be dry.  The mass is then passed through calenders heated to about 100 DEG  C. until the mixture attains a constant weight.  This results in a mass of disintegrated fibres evenly impregnated with rubber.  The dispersion should be one which readily coagulates, and the leather should not be acid, treatment with alkali being applied if necessary, to ensure this.  The mass p  may be sheeted, or may be used as an ingredient in rubber mixes. Vulcanizing, colouring, filling agents may be added to the dispersion.  Tanning agents or birch oil may be added at any stage to produce a smell of leather.

Title: Improvements in or relating to circuit-arrangements for producing direct voltage
IPC: H04N3/185
Filed: 1950-10-16
Abstract: 673,783. Automatic voltage control for rectifying systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 16, 1950 [Oct. 15, 1949], No. 25164/50. Classes 38 (ii) and 38 (iv). A circuit arrangement for producing direct voltage by rectification of the pulses appearing across an inductance coil and a capacity, which may be the coil self-capacity, in parallel therewith, the coil being included in the anode circuit of a discharge tube which is periodically cut-off has means for maintaining the generated direct voltage constant irrespective of the load which are characterized in that the discharge tube is controlled by pulses, the duration of which are dependent upon the load. An inductance coil 18 is placed in the anode circuit of a discharge tube 14 which is controlled by the multivibrator 11 by means of a series of positive and negative square-shaped pulses applied to the grid 16 of the discharge tube 14. The high voltage generated in the inductance coil 18 when the tube 14 is cut off is rectified and stepped up by the voltage multiplier 13 and then applied to the accelerating anode of a cathoderay tube 60, and the potentiometer 23. Variation in the load current, i.e. the beam current of the cathode-ray tube 60, causes the potential across the resistor 47 to alter, thus altering the mark-space ratio of the output waveform of the multivibrator 11, causing the final value of the anode current in the tube 14 to vary such that on cut-off of the tube the direct voltage generated in the coil 18 and multiplier 13 remains constant, thus keeping a constant potential across the load 23. Negative synchronization pulses for the multivibrator 11 are applied at the point 20 and may be derived from the horizontal deflection coils 65. If no synchronization pulses are received no pulses will be supplied to the tube 14 so that no direct voltage is generated this safeguarding the screen of the cathode-ray tube.

Title: Improvements in and relating to 2,5-substituted 2,5-dihydrofurans
Filed: 1950-10-19
Abstract: 2,5-Substituted 2,5-dihydrofurans having the general formula <FORM:0682736/IV (b)/1> where R1, R2, and R4 are hydrogen, alkyl-(including substituted alkyl), aryl-, aralkyl-, or alicyclic or heterocyclic groups, and R5 is an alkyl group or a substituted alkyl group, are produced from furans by oxidation and 2,5-substitution, in which the oxidation is carried out electrolytically in a solution of the furan in an organic solvent. The oxidation may take place due to the presence of a halogen compound in the solution to be electrolysed.  A solution of a furan or furan derivative in an alcohol may be electrolysed in the presence of an ammonium halide such as ammonium bromide, or a hydrohalide of an amide, such as morpholine hydrobromide.  As an example ammonium bromide is dissolved in methanol and mixed with freshly-distilled furan.  The mixture is treated electrolytically and the contents of the cell are afterwards poured on to a solution of sodium methoxide.  The mixture is distilled until methanol containing ammonia and surplus furan are removed.  The residue is then filtered and the filtrate is distilled to produce crude dimethoxy-dihydrofuran which is purified by fractional distillation.  Other examples are given of the electrolytic production of 2,5-dimethoxy-2,5-dihydrofurfurylalcohol from an electrolyte containing ammonium bromide, methanol and freshly-distilled furfuryl alcohol, 2,5-dimethoxy-2,5-dihydrosylvan from an electrolyte which includes freshly-distilled sylvan, 2,5-di-isopropoxy-2,5-dihydrofuran from an electrolyte containing ammonium bromide, iso-propanol, and furan, 2,5-di-n-propoxy-2,5-dihydrofuran from an electrolyte containing acetyl bromide, n-propanol and diethanolamine, and 2,5-dimethoxy-2,5-dihydrofurfurylmethylether from an electrolyte containing ammonium bromide, methanol and freshly-distilled furfurylmethylether.
